Michael Emerson is an acting god. Just go back and watch this scene if you want definitive proof. Lost, once again, showed us why it is unlike any other series on television. We've seen the hostage stand-off scenario thousands of times by now, but I can honestly say that never has it been executed better than when Keamy held Alex, Ben's daughter, at gun point. Ben did not back down, and Keamy shot Alex in the head, killing her. It was perfectly paced, expertly acted, and provided a huge shock (did they really just do that?) and some of the best acting you'll ever see. The range of emotions displayed by Michael Emerson was simply astonishing.
